COPYING-PRESS.

SPECIFICATION forming part of Letters Patent N0. 764,694, dated July 12,1904.

Application filed May 7,1903. semi No. 156,098. (No inode To (/,ZZ whomlit may concern:

Be it known that I, GEORGE H. TAYLOR, a citizen of the United States,residing at Norfolk, in the county of Norfolk and State of' Virginia,have invented certain new and useeration, and comparatively inexpensiveVof production.

W'ith this and other objects inview the in-` vention consists of certainnovel features of" construction, combination, and arrangement of parts,as will be hereinafter more fully described, and particularly pointedout in the appended claims, reference being had to the accompanying'drawings` in which- Figure 1 is a perspective view of my im-f Fig. 2 1sa verticalI proved copying-press. longitudinal sectional view throughthe same. Fig. 3 is a cross-sectional view taken on the line 3 3 o'fFig. 2. Fig. 4 is a horizontal sectional view taken on the line 4 4 ofFig. 2,' and Fig. 5 is a detail vertical sectional view taken on theline 5 of Fig. 4.

Referring to the drawings in detail, the numeral 1 denotes a casing orframe within which the operating parts of my invention are mounted. Saidcasing consists of the two sides Q, secured to the base or bottom 3 andhas both of its ends open. The top of the casing at the rear ordischarge end is open; but the forward end of the top is adapted to beclosed by the removable cover 4, which is inclined downwardly toward thecenter of the machine to facilitate the feeding of the letters, ashereinafter explained. The cover 4 has its side edges slidably engagedwith grooves 5, formed in the sides 2 of the casing. At about thecenter' of the casing and transversely disposed above the same is aroller 6, of any suitable material of an elastic nature, preferfaces ofthe sides 2 of the casing.

ably ,soft rubber. Said roller hasits shaft 7 journaled in suitablebearings formed in the sides 2 of the casing at opposite points. 4 Onone end of said shaft 6, upon theoutside of the casing, is secured acog-wheel or gear 8 of large diameter. The gear 81's in mesh with and isdriven by a small cog-wheel or pinion 9, which is journaled upon astub-shaft 10, projecting from the side of the casing. An operatingcrank-handle 11 is secured to said pinion 9. It will be seen byproviding the small pinionwith its operating-handle and gearing the samewith the large gear that the latter may be readily and easily turnedtorotate the roller 6 and feed the letters, as hereinafter described.`YIn line with and below the roller 6 is a pressure-roller'12,preferably of hard or vulcanized rubber, The ends of the shaft 13 ofthis roller are engaged with-or slidably mounted in vertical grooves 14,formed upon the inner These grooves communicate with the grooves 15,which extend rearwardly and then upwardly to the top of the sides 2 topermit of the removal of the roller, as will be readily understood. Theroller 12 is supported in the vertical grooves 14 and is forced upagainst the upper roller6 by the springs16. YOne end of each of these'springs is bolted, riveted, or otherwise securedto thel inner faces ofthe sides 2, as seen at 17, and the opposite` ends of said springs arebent to form the curved seats or bearings 18, whichv receive the ends ofthe shaft`13..l The pressure which these springs exert to force theroller 12 against the roller 6`may be varied and regulated in anydesired manner. I preferably provide a transverse regulating or reliefbar or shaft 19, which is operated by the lever 2Q. This relief-bar hasits vends journaled in the sides 2- of the casing and is provided withthe cams or semicircular enlargements 21, which engage or bear upon thesprings 16. The handlever 20, which is of spring metal, is secured toone end of the shaft outside of the casing. It will be readily seen thatwhen the lever 2O is pressed downwardly toward the base of the machinethese cam portions or semicirlcular swellings 21 will come in contactwith IOO ally diminish the pressure exerted by the springs upon theshaft of the roller 12. By thus operating the lever 20 the lower roller12 may be made to bear with any desired pressure against the upperroller 6. Any desired means may be employed to hold .the lever in 1 anadjusted position'. I preferably provide one of the sides 2 at the frontend with a series of notches or teeth 22, with which they By pressingthis lever outwardly away from the teeth spring-lever 20 may beengaged.y

it may be moved up or down to the desired position, and when released itwill spring in towardthe teeth, and thus be locked against casualdisplacement.

VV-hile l have described and illustrated the preferred-a-rrangementofthe pressure-springs and relief-bar, it will be understood that Ido notlimit myself to this construction. Any arrangement of springs andrelief-bar upon either one or Aboth of the roll-ers for relieving andregulating the pressure of the rollers can be used.

Passing around said roller l2 and around a Asecor-id roller 23 is anendless Ebe-l-t 24, of some absorbent material, `such as cloth orfabric. The roller is of much less diameter than the roller l2 and is'disposed across the rear end of the casing. lt is also disposed so thatits axis is above the axis of the roller 12, but that the upper portionof i-ts periphery is line or approximately in line with the upperportionof the periphery-of said roller 12.

By this arrangement of the rollers it will be,

observed that the belt l is so extended that the upper portion thereofis horizontally 4arranged between the two rollers and forms a lstraightmoistening stretch, while the lower portion thereof is inclined upwardlyfrom the roller 12 to the roller 23 to form an angularly-disposed returnstretch, thus producing an acute `angle at the delivery end of thebeltviz., at that end at which the roller 23 is located. rlhe roller 23isjournaled so as to .be adjusted toward and from the roller 12, for apurpose hereinafter explained. This is preferably done by providing eachend of said roller with the journals or trunnions `25, which are engagedby or seated in the forked or hif-ureated ends 26 of the screws 27. Eachlscrew27 passes through the apertures 28 and a slot 29 formed in. theside 2 of the casing. An operating-nut 30 upon said screw is `'disposedin said slot l29 to prevent it having longitudinal movement. When thenut is rotated, it will be seen lthat the screw 27 will be movedlongitudinally, and thus adju-st the small roller 24, as will 'bereadily understood upon reference to Figs. 4 and 5 of the drawings.

The roller 12. is adapted to project into a receptacle or pan 31,containing water other liquid. =Said pan is supported beneath the rollerin any desired manner, but preferably by means of a removable shelf 32,which sli-des longitudinally in grooves cut in the sides 2 of thecasing. By reason of this sliding movement it Will be noticed that theend 33 of the pan may be moved so as to engage the fabric belt upon theroller 12 and scrape or remove the ysuperti-uous amount of water fromthe same.

The tissue 33, upon which the copy is to be made, is rolled in acontinuous sheet or web upon a shaft or roller 34. If desired, l maymake the roll of paper of a number of sheets of any desired size, withtheir ends pasted or attached together by some soluble mucilage orcement in order to form a continuous web. When the tissue is moistenedby passingover the wet band or fabric belt, the mucilage is dissolved,and the sheet -upon which the copy is made may be pulled loose from thenext sheet, thus permitting the copy to be taken from the machine withthe letter which has been copied. The roll of tissu-e is disposed in thefront portion of the casing beneath the cover 4. The ends of the shaft34 engage the vertical guides or grooves 35, formed upon the inside ofthe casing,andslidedownwardly in the same when said roll is unw-ound. asthe paper is used. The web of copying-tissue 33 passes from the rollund-er t'he transversely- Idisposed relief-bar, which acts as a guidefor i the tissue, and then up over the fabric belt between th-e rollersand 12.

In the operation of the machine when the parts are properly .adjustedthe letter or sheet 3'6, -a copy of which is desi-red, is inserted, asshown in Fig. '2, between the rollers 46 and 12, and. theoperating-handle 1l is turned to feed `said letter between the `upperroller 6 and the web ofcopying-tissue, which has become :m oistened bycontact with the absorbent belt 24. The hel-t as it passes through thewater in the pan beneath the roller 12 'becomes thoroughly saturated inorder to dampen the copyingtissue The `amount off water that the bandcarries up over the roller 12 is regulated by adjusting the small roller23 by means of the nuts 30 and screws 27, which act upon the smallroller 23 to tighten .or loosen the fabric band or belt. lt will bereadily seen that when the band is loose it will absorb and carry vmorewater than when it is tightly stretched. The pressure of the roller 12may be easily regulated by means of the lever 20, as previouslydescribed, rand as the sheet or letter which is being copied passesbetween the rollers it will be carried rearwardly by the belt anddischarged at the end of the machine. When the pressure of the spring'on the r-ollers 6 and 12 is removedl by throwing the lever 2O down toits lowest position, the roller 12 may be easily removed from the casinglby allowing the ends of its shaft to slid-e in the grooves 15, vandthus a new belt may be placed upon the rollers to replace a worn-out oneor to otherwise repair and clean out the machine. v

Owing to the small size of the roller 23 and the acute angle of the beltformed thereby, the copying-tissue and letter will not stick to the beltand be carried back into the casing, but will be disengaged therefromand pass over the rear end of the casing. It will be seen that byproviding the fabric belt upon the large pressure-roller and the smalladjusting-roller QB'and passing the same through the water in the panthe copying-tissue will be thoroughly and evenly dampened on the copyingside, and a very simple and efficient machine is thus produced. rIheband or belt contacts with and moistens the under side of the tissue, sothat the water will soak through the same to form an evenly-moistenedupper or copying side, and thereby permit a perfect copy of the letterto be made.

It will be understood that while I have illustrated and described thepreferred arrangement of the fabric band and the rollers 6, l2, and 23various other arrangements of these parts may be had for accomplishingthe same results, and I do not care to be limited to the preciseconstruction shown and described.

From the foregoing description, taken in connection with theaccompanyingdrawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.
